That is absolutely right, KG. There is no correct option among the answers to question 5.
Thank you for you comments, you are absolutely right and the error has been fixed.
There is an error in the 5th question. Mrs Jennings can be tactless and vulgar, but she is the reverse of cold-hearted and selfish. The person who bonds with Mrs John Dashwood because both possess these qualities is not her but her daughter Lady Middleton.
